About Traumatic Knee Injuries

Trauma-related arthritis is the third most common cause of joint damage. It results from damage to the joint from a previous injury. After the injury, bone and cartilage may not heal properly which can lead to:

• Joint losing its natural smooth surface
• Excessive wear on the joint surface
• Negative impact on the blood supply to the joint
• Arthritis
• Osteonecrosis or avascular necrosis (AVN)—deterioration of the bone due to a lack of blood supply

Up to 20,000 new cases of AVN are reported each year. AVN is a disabling condition that can cause:

• Loss of flexibility and strength
• Development of bone spurs
• Knee pain
• Joint damage
• Loss of movement
• Knee joint collapsing

If you are diagnosed with AVN, certain medical procedures may help your body build new blood vessels and bone cells to replace the dead ones. If AVN has progressed, knee replacement surgery may reduce your pain and give you better mobility.
